14 Claims.

This invention relates to boxes particularly adapted for holding rollsof wrapping paper in such a manner that any desired length of the papermay be drawn out as required and cut off against a tearing edge formedon or carried by the box, and my object is to devise a simple andefficient box for this purpose which will be cheap .to produce,convenient and eflicient in operation and which may be stored inknock-down condition.

I attain myobject by means of a construction which may be brieflydescribed as follows. The box comprises an open topped body portion, anda cover hinged to the body portion and provided with a depending frontand ends. The parts are preferably integral and formed from a foldedblank.

A special feature of the cover is that its front is formed-of a partintegral with the top and the ends, the inner part of the front beingformed with a secondary flap adapted to lie against the under surface ofthe top.

Another object is the provision of an inexpensive cardboard containercarrying a paper roll from which paper is withdrawn through thepassageway formed between the front of the cover and the front of thelower portion of the container. The front wall of the cover ispreferably folded inwardly upon itself providing an upwardly angularlyextending primary flap which yieldingly urges the paper Web against thefront wall of the lower portion of the container and acts as a brakeupon the movement of the paper web while permitting the withdrawalthereof. The folded edge provides a hard smooth reinforced cutting edgeagainst which the paper may be 'severed. This infolded primary flap istensioned upon closure of the cover and, upon release of the cover, ittends to assist in lifting the cover to expose the end of the paper webso that it may be readily grasped for further withdrawal.

A special feature of the box is that the ends of the front and back areprovided with interlocking flaps and that these flaps are embraced bythe parts of end members folded on themselves and preferably providedwith flaps adapted to lie against the bottom of the box.

The invention is hereinafter more fully de scribed, and is illustratedin the accompanying drawing in which Figure 1 is a cross section of. thecontainer constructed in accordance with my invention with 55 the coverin closed position,

folded on itself to embrace flaps integral with.

the cover partly Figure 4 a perspective detail showing more particularlyone corner of the cover partly unfolded;

Figure 5 a perspective view of part of the container showing moreparticularly one end with the parts partly unfolded, and

Figure 6 a longitudinal section partly broken away.

In the drawing like numerals of reference indicate corresponding partsin the different figures.

Referring to the drawing, it will be seen that the container comprisestwo main parts, an open. top box and a cover, the one hingedly connectedto the other at the top rear edge of the box. Preferably these two partsare integral, being formed from a cardboard blank which will be scoredalong the line 1 to facilitate bending at that point.

The open top box comprises a bottom 2, front and back walls 3 and 4integral with the bottom, end flaps 5 integral with the front and backwalls and-ends 6 integral with the bottom and folded on themselvestoembrace the end flaps and thus stifien the box ends, and provide smoothunbroken outside surface for printing. The end flaps, as will be seenparticularly on reference to Figs. 5 and 6, are interlocked in a knownmanner to hold the front and back walls in the set up position.Preferably each end 6 has a flap 7 formed on its free edge adapted tolie on the bottom of the box. These flapssupport the ends of the roll ofpaper and lessen the frictional resistance to the turning of the roll ascompared with contact for its full length on the bottom of the box.

The cover comprises the top 8, the ends 9, preferably triangular andintegral with the top, and the front 10 integral with the front edge ofthe top. This front is folded on itself forming a primary flap adaptedto embrace the end flaps 11 which are integral with the ends 9, whilethe front as a whole is held rigidly positioned by the ends 9. Asecondary flap 12 is formed on the free edgeof the primary flap or theinner part of the double front, which secondary flap is adapted to lieagainst the under surface of the top of the cover as shown in Figure 1.The fold of this double front forms a stiff reinforced tearing edgewhich makes it unnecessary to use metal to form the tearing edge, Thisfold forms a smooth hard cutting edge superior to the raw edge of asingle thickness of cardboard. While the flap 12 might be secured to theunder surface of the top 8 I prefer. to leave it free, as shown thespringinass of the folded front to hold the portion of a roll of paperwhich is being drawn out against the free edge of the front of the box,thus tending to prevent its passing back into the box. Another advantagein leaving the double front free is that the lid will retain aslightlyraised position when desired to give access to the free end of the webdrawn off from the roll. Within the lower portion of the container isdisposed for unwinding a roll of paper as shown in Figures 1 and 2.

The element 10 as shownin Fig. 1 is folded upon itself and due to itsinherent resilience, bears upon the front face of wall 3, exerting aforce normal to that wall which may be assumed to act at a point midwayof the depending dimension of the element 10. The force thus exertedgives rise to an equal and opposite reaction by the wall 3 upon element10. Treating the cover portion of the box as a free body and taking asummation of moments about the hinge axis at 1, the reaction force ofthe wall 3 upon the element 10 produces a clockwise moment about axis 1equivalent to the product of the forceabove in pounds and half the depthof the depending element 10 in inches. The opposing moments are due tothe friction between element 10 and wall 3, and the weight of the covermultiplied by their respective moment arms. The factors of force due toresilience, the coefiicient of friction between the surfaces, weight andthe length of the moment arms, are so correlated as to give a resultantclockwise moment which will effectively raise the cover.

From the above description it will be seen that I have devised acontainer which will satisfactorily attain the objects of my inventionas set out in the preamble of this specification.
